A side project of singer/songwriter Andrew Mcmahon. Basicaly a solo project produced from the help of many other people including Tommy Lee on drums! Mcmahon uses his unique voice, powerful lyrics, and the heartfelt rithyms of his ever so famous piano. With a full album out now they are a great band to listen to whether your happy or sad. Basically Something Corporate with a little twist of pop flavor. For more info see Andrew Mcmahon or Something Corporate.
One hell of a kick ass side project sure to rock you. Jacks Mannequin is awsome

A side project of Andrew McMahon that is actually written with out the apostrophe, just Jacks Mannequin
Andrew said in an interview that it was actually Jacks Mannequin instead of Jack's Mannequin.

Piano Rock, to rock out on a grand piano, upright or keyboard. Kicking over your bench or seat and pounding some ivorys. A Jack's Mannequin might also exhibit the compulsion to dance on a piano.
That band is trying to play some Jack's Mannequin

The perfect shade of "dark blue." Which may or may not be found in a box of crayons.
Oh, would you look at that? Tonight's the prefect shade of Jack's Mannequin.
